Call My Bluff is designed for up to six individual players or two teams. Insert a cassette into the game console. Stand by your button as the emcee announces each question. The first player to hit the button gets to answer. But listen carefully - is it a bluff? Should you challenge? It's up to you. You'll get points if you're right, lose points if you're wrong. The digital display automatically registers each player's points. Call My Bluff is a trivia game that involves a large console with a cassette tape player. Special cassettes indicate to the console how many points a player gets for answering the question correctly (as some of the questions are worth more points than others.) While the game was published by Charan Toys, the cassette technology was licensed from Words of Wonder, the company responsible for the hugely successful Teddy Ruxpin series of toys.
